The smartphone features an 8 megapixel rear camera with a 28mm lens, f2.0 aperture and a backside illuminated sensor for better image quality in low-light conditions. There is a secondary front facing 2.1 megapixel camera which can record in 1080p resolution.

The company has not yet revealed which version of Android will the device be running. Also, so far there is no word on the pricing and availability of this device.

"We are confident that HTC Butterfly will set a new example for high-end smartphones," chief executive Peter Chou said at the launch in Taipei.

HTC sells its own smartphones and also makes handsets for a number of leading US companies, including Google's Nexus One.

The company has recently unveiled a new series of smartphones as it faces intense competition from Apple and South Korea's Samsung and seen its third quarter profit tumble 79.1 percent year-on-year.

HTC and Apple were locked in more than 20 patent lawsuits worldwide until the two firms reached a global patent settlement last month. The world's leading technology firms have routinely pounded each other with patent suits.
